Must say I'm quite impressed. A sintered filter and a one way valve on the fluid line. Two needle valves and a 5/16" air line push fit. Rigged it up to a small air brush compressor and it works a treat. Obviously I need a bigger compressor to get max air flow but the venturi works even at air brush outputs.

First make it to work, then be impressed. I did my first one using chinese needle valve for 5$ and it ended breaking seal after 5 min. Now i use Italian made valve and have not had any problems since. Valve must be good or it will not work properly.
